Development of Analytical Method for the Quantitation of Monoclonal Antibodies Solutions via Raman Spectroscopy: The Case of Bevacizumab. Pharmaceuticals (Basel) 2024; 17:446. [PMID: 38675406 PMCID: PMC11055105 DOI: 10.3390/ph17040446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 03/08/2024] [Accepted: 03/28/2024] [Indexed: 04/28/2024] Open
Abstract
Personalized dosages of monoclonal antibodies are being used more regularly to treat various diseases, rendering their quantitation more essential than ever for the right dose administration to the patients. A promising alternative, which overcomes the obstacles of the well-established chromatographic techniques regarding the quantification of biopharmaceuticals, is Raman spectroscopy. This study aimed to develop and validate a novel analytical method for the quantitation of bevacizumab in solutions via Raman spectroscopy. For this purpose, a droplet of the solution was left to dry on a highly reflective carrier and a home-made apparatus was employed for rotation of the sample. Hence, each recorded Raman spectrum was the average of the signal acquired simultaneously from multiple points on a circular circumference. The method was validated, and the detection limit of the antibody was found to be 1.06 mg/mL. Bevacizumab was found to be highly distributed at the formed coffee ring of the dried droplet, though this was a function of solution concentration. Finally, Raman spectra at different distances on the coffee ring were obtained from the four quarters. The lowest bevacizumab detection limit was found at a distance of 75 μm from the external side of the coffee ring and it was determined to be equal to 0.53 mg/mL.

Abstract
Pericarpium Citri Reticulatae (PCR) is used in food and medical herbal formula, and its quality is determined by its age. Raman spectroscopy is a laser technology for molecular fingerprinting. The feasibility of using surface-enhanced Raman spectroscopy (SERS) to determine the PCR age was investigated. The Raman peaks were acquired using a Raman spectrometer with a 785 nm diode laser and were analyzed using principal component analysis (PCA) followed by linear discriminant analysis (PCA-LDA). There were six major peaks at 600, 730, 990, 1370, 1607, and 1742 cm-1 in the SERS spectra, and their intensity, especially the peak at 1607 cm-1, was inversely correlated with the PCR age. The different ages of PCR could be correctly classified with over 90 % accuracy by using PCA-LDA based on the SERS spectra. In conclusion, a Raman spectrometer may be used as a novel method to identify the age of PCR products.

Abstract
The drug release profile of drug-eluting stents (DESs) is affected by a number of factors, including the formulation, design, and physicochemical properties of the utilized material. DES has been around for twenty years and despite its widespread clinical use, and efficacy in lowering the rate of target lesion restenosis, it still requires additional development to reduce side effects and provide long-term clinical stability. Unfortunately, for analyzing these implants, there is still no globally accepted in vitro test method. This is owing to the stent's complexity as well as the dynamic arterial compartments of the blood and vascular wall. The former is the source of numerous biological, chemical, and physical mechanisms that are more commonly observed in tissue, lumen, and DES. As a result, universalizing bio-relevant apparatus, suitable for liberation testing of such complex implants is difficult. This article aims to provide a comprehensive review of the methods used for in vitro release testing of DESs. Aspects related to the correlation of the release profiles in the cases of in vitro and in vivo are also addressed.

Abstract
Raman Spectroscopy is well emerged in the field of Analytical Quality Control (AQC) as a rapid and cost-effective technique useful in many applications. The advantage of Raman spectroscopy is the non-invasiveness of measurements that enablesto analyse samples directly in its container. In this study, the potential of Raman spectroscopy was investigated for analysis of clinical preparations of mAbs. Three commercial formulations of monoclonal antibodies (mAbs) Avastin®, Ontruzant® and Tecentriq® corresponding to Bevacizumab (BVC), Trastuzumab (TRS) and Atezolizumab (ATZ) respectively, were analysed in quartz cuvette in macroscopic analysis and through the wall of perfusion bags in microscopic analysis. The spectra have been compared to those of excipients (trehalose and sucrose) and of γ-Globulin, in order to investigate the origin of Raman bands. As expected, Raman spectra were a combination of bands from monoclonal antibodies and correspoding excipients found in formulas. For quantitative analysis of the solutions, models have been constructed using Partial Least Square Regression (PLSR) with Leave K-Out Cross Validation (LKOCV). The quantification performance was comparable for both macroscopic and microscopic analysis, in terms of error and linearity. The results are thus promising for future AQC in situ, in perfusion bags.

Analysis of IV Drugs in the Hospital Workflow by Raman Spectroscopy: The Case of Piperacillin and Tazobactam. Molecules 2021; 26:molecules26195879. [PMID: 34641421 PMCID: PMC8513103 DOI: 10.3390/molecules26195879] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 09/22/2021] [Accepted: 09/23/2021] [Indexed: 11/29/2022] Open
Abstract
Medical errors associated with IV preparation and administration procedures in a hospital workflow can even cost human lives due to the direct effect they have on patients. A large number of such incidents, which have been reported in bibliography up to date, indicate the urgent need for their prevention. This study aims at proposing an analytical methodology for identifying and quantifying IV drugs before their administration, which has the potential to be fully harmonized with clinical practices. More specifically, it reports on the analysis of a piperacillin (PIP) and tazobactam (TAZ) IV formulation, using Raman spectroscopy. The simultaneous analysis of the two APIs in the same formulation was performed in three stages: before reconstitution in the form of powder without removing the substance out of the commercial glass bottle (non-invasively), directly after reconstitution in the same way, and just before administration, either the liquid drug is placed in the infusion set (on-line analysis) or a minimal amount of it is transferred from the IV bag to a Raman optic cell (at-line analysis). Except for the successful identification of the APIs in all cases, their quantification was also achieved through calibration curves with correlation coefficients ranging from 0.953 to 0.999 for PIP and from 0.965 to 0.997 for TAZ. In any case, the whole procedure does not need more than 10 min to be completed. The current methodology, based on Raman spectroscopy, outweighs other spectroscopic (UV/Vis, FT-IR/ATR) or chromatographic (HPLC, UHPLC) protocols, already applied, which are invasive, costly, time-consuming, not environmentally friendly, and require specialized staff and more complex sample preparation procedures, thus exposing the staff to hazardous materials, especially in cases of cytotoxic drugs. Such an approach has the potential to bridge the gap between experimental setup and clinical implementation through exploitation of already developed handheld devices, along with the presence of digital spectral libraries.

Abstract
Analytical Quality Control (AQC) in centralised preparation units of oncology centers is a common procedure relying on the identification and quantification of the prepared chemotherapeutic solutions for safe intravenous administration to patients. Although the use of Raman spectroscopy for AQC has gained much interest, in most applications it remains coupled to a flow injection analyser (FIA) requiring withdrawal of the solution for analysis. In addition to current needs for more rapid and cost-effective analysis, the risk of exposure of clinical staff to the toxic molecules during daily handling is a serious concern to address. Raman spectroscopic analysis, for instance by Confocal Raman Microscopy (CRM), could enable direct analysis (non-invasive) for AQC directly in infusion bags. In this study, 3 anticancer drugs, methotrexate (MTX), 5-fluorouracil (5-FU) and gemcitabine (GEM) have been selected to highlight the potential of CRM for withdrawal free analysis. Solutions corresponding to the clinical range of each drug were prepared in 5% glucose and data was collected from infusion bags placed under the Raman microscope. Firstly, 100% discrimination has been obtained by Partial Least Squares Discriminant Analysis (PLS-DA) confirming that the identification of drugs can be performed. Secondly, using Partial Least Squares Regression (PLSR), quantitative analysis was performed with mean % error of predicted concentrations of respectively 3.31%, 5.54% and 8.60% for MTX, 5-FU and GEM. These results are in accordance with the 15% acceptance criteria used for the current clinical standard technique, FIA, and the Limits of Detection for all drugs were determined to be substantially lower than the administered range, thus highlighting the potential of confocal Raman spectroscopy for direct analysis of chemotherapeutic solutions.

Qualitative and quantitative analysis of therapeutic solutions using Raman and infrared spectroscopy. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2019; 218:97-108.

Abstract
Anticancer drugs are prescribed and administrated to an increasing number of patients on a daily basis. As a consequence, a number of concerns have been raised about the patient health and safety in the case that the drugs administered are not at the required concentration or even worse not the correct ones. Quality control of therapeutic solutions has therefore been extensively implemented in hospital environments, in order to avoid any failure in the intense workflow faced by administering pharmacists. In the present study, infrared (IR) and Raman spectroscopy have been employed for the analysis of 3 commercially available therapeutic solutions TEVA®, MYLAN®, CERUBIDINE®, respectively containing doxorubicin, epirubicin and daunorubicin. They perfectly illustrate the analytical difficulties encountered, as these 3 chemotherapeutic drugs are isomers, hardly distinguishable with conventional approaches such as UV/VIS spectrometry. Any analytical failure to identify these molecules can lead to delays in patient treatment. While Partial Least Squares Regression analysis demonstrates that both Raman and IR can deliver satisfactory quantitative analysis in the clinical range, with respective Root Mean Square Error of Cross Validation (RMSECV) between 0.0127 - 0.0220 g·L-1 and 0.0573 - 0.0759 g·L-1, the identification rate between the 2 techniques differs substantially. Indeed, Principal Component Analysis - Factorial Discriminant Analysis (PCA-FDA) highlights that, depending on the data preprocessing applied to Raman spectra, the discrimination between the 3 drugs is decreased, with in some cases specificity and sensitivity below 50%. However, IR analysis displays encouraging results with an overall specificity and sensitivity between 99 and 100%, suggesting that reliable validation of the therapeutic solution for administration to patients can be achieved. IR and Raman spectroscopy could assist and support quality control of chemotherapeutic solutions prepared in personalised concentrations for each patient. The effective and reliable characterisation of therapeutic solutions could have a lot to offer to improve current practices in a near future.

Abstract
Parametric release was the first subset of real time release testing (RTRT), applied to terminally sterilised injectable drug products. The objective was to offer the industry an alternative to the time and money consuming sterility testing, without compromising the sterility of the products. The rationale was that quality cannot be tested into products, instead it must be planned (the principle of quality by design, QbD). This can be implemented by setting appropriate in-process controls supported on process analytical technologies (PAT). Two of the most versatile and promising PAT tools are the near infrared spectroscopy (NIRS) and the Raman spectroscopy. However, their application to injectable drug product development and manufacturing has been scarce. This review has the objective to provide a framework for the practical implementation of the QbD approach to injectable formulations, including application of diverse risk assessment and factorial design tools. Finally, the actual application of PAT, namely NIRS and Raman spectroscopy, to injectable drug product analysis is addressed.

Abstract
The aim of this study was to assess the ability of Raman spectroscopy to discriminate and quantify five antineoplastic drugs in an aqueous matrix at low concentrations before patient administration. Five antineoplastic drugs were studied at therapeutic concentrations in aqueous 0.9% sodium chloride: 5-fluorouracil (5FU), gemcitabine (GEM), cyclophophamide (CYCLO), ifosfamide (IFOS) and doxorubicin (DOXO). All samples were packaged in glass vials and analyzed using Raman spectrometry from 400 to 4000cm-1. Discriminant analyses were performed using Partial Least Squares Discriminant Analysis (PLS-DA) and quantitative analyses using PLS regression. The best discrimination model was obtained using hierarchical PLS-DA models including three successive models for concentrations higher than the lower limit of quantification (0% of fitting and cross-validation error rate with an excellent accuracy of 100%). According to these hierarchical discriminative models, 90.8% (n=433) of external validation samples were correctly predicted, 2.5% (n=12) were misclassified and 6.7% (n=32) of the external validation set were not assigned. The quantitative analysis was characterized by the RMSEP that ranged from 0.23mg/mL for DOXO to 3.05mg/mL for 5FU. The determination coefficient (R2) was higher than 0.9994 for all drugs evaluated except for 5FU (R2=0.9986). This study provides additional information about the potential value of Raman spectroscopy for real-time quality control of cytotoxic drugs in hospitals. In some situations, this technique therefore constitutes a powerful alternative to usual methods with ultraviolet (UV) detection to ensure the correct drug and the correct dose in solutions before administration to patients and to limit exposure of healthcare workers during the analytical control process.

Abstract
AbstractTo assess the quality of centrally prepared cytotoxics a global approach is being implemented by pharmacists. A risk analysis is performed, and then many in-process controls are proposed. The aseptic process and the material are also fully validated. Moreover the skills of pharmacy technicians are being checked and monitored over time. This short opinion paper discusses the place of in-process quality control within the quality system applied to cytotoxic preparations. It also discusses the pros and cons of analytical control of the final product versus continuous control of each preparation step by eye witness or an electronic device such as a camcorder. Finally the relevancy of controls is discussed in function of different cases and of the human and material resources available in the pharmaceutical technology cytotoxic unit.

Abstract
Raman spectroscopy is a rapid, non-destructive and non-invasive method that is a promising tool for real-time analytical control of drug concentrations. This study evaluated a handheld Raman device to discriminate and quantify two isomeric drugs used to treat cancer. Doxorubicin (DOXO) and epirubicin (EPIR) samples were analyzed at therapeutic concentrations from 0.1 to 2mg/mL (n=90) and 0.08-2mg/mL (n=90) by non-invasive measurements using a portable Raman spectrometer. The discrimination of these two molecules was demonstrated for all concentrations (n=180) by qualitative analysis using partial least square discriminant analysis (PLS-DA) with 100% classification accuracy, sensitivity and specificity and 0% error rate. For each molecule, quantitative analyses were performed using PLS regression. The validity of the model was evaluated using root mean square error of cross validation (RMSECV) and prediction (RMSEP) that furnished 0.05 and 0.02mg/mL for DOXO and 0.17 and 0.16mg/mL for EPIR after pretreatment optimization. Based on the accuracy profile, the linearity range was from 1.256 to 2.000mg/mL for DOXO (R2=0.9988) and from 0.553 to 2.000mg/Ml for EPIR (R2=0.9240) and repeatability (CV% max of 1.8% for DOXO and 3.2% for EPIR) and intermediate precision (CV% max of 2.8% for DOXO and 4.5% for EPIR) were both acceptable. Despite the narrow validated concentration range for quantitative analysis, this study shows the potential of a handheld Raman spectrometer coupled to chemometric approaches for real-time quantification of cytotoxic drugs, as well for discriminating between two drugs with similar UV absorption profiles. Finally, the use of a handheld spectrometer with the possibility of a direct measurement of substances in containers is a potentially valuable tool for combining patient safety with security of healthcare workers.

Abstract
DrugCam(®) is a new approach to control the chemotherapy preparations with an intelligent video system that enables automatic verification during the critical stages of preparations combined with an a posteriori control with partial or total visualization of the video recording of preparations. The assessment was about the recognizing of anticancer drug vials (qualitative analysis) and syringe volumes (quantitative analysis). The qualitative analysis was conducted for a total of 120 vials with sensitivity of 100% for 84.2% of the vials and at least 97% for all the vials tested. Accuracy was at least 98.5% for all vials. The quantitative analysis was assessed by detecting 10 measures of each graduation for syringes. The identification error rate was 2.1% (244/11,640) i.e. almost 94% to the next graduation. Only 3% (35/1164) of the graduations tested, i.e. 23/35 for volume <0.13 ml of 1 ml syringes, presented a volume error outside the admissible limit of ± 5% of a confidence band constructed for the estimated linear regression line for each syringe. In addition to the vial detection model, barcodes can also read when they are present on vials. DrugCam(®) offers an innovative approach for controlling chemotherapy preparations and constitutes an optimized application of telepharmacy.

Abstract
In France, chemotherapy preparation units of hospital pharmacy compound cytotoxic infusion bags adapted to each patient. The narrow therapeutic index of these preparations led us to implement qualitative and quantitative control for patients' safety. To this aim, we calibrated an equipment combining UV-vis spectrometry and Raman spectroscopy (QC Prep+) and monitored 14 different molecule-solvent combinations over a 18 months period. This rapid and specific method allowed the qualitative and quantitative analysis of 1 mL sample tests in less than 2 min. On 5742 anticancer preparations, we obtained accepted results with more than 99.4% solvent identification, 99.6% drug identification and only 1.52% of preparations not matching quantitative specifications (±15% of theoretical concentration). This quantitative control enabled us to pinpoint some critical points of production for two of the most common preparations. We thus updated the procedures of reconstitution and preparation, increasing the quality of final product. UV-Raman spectrometry is thus an effective tool to control chemotherapy infusions and to improve good practices of preparation.

Abstract
Abstract: Musculoskeletal disorders (MSD) remain the most common occupational disease in the Western countries. Beside the effects on workers themselves, MSDs may lead to high costs to enterprises and the society as a whole. Among the painful or tiring positions encountered in healthcare settings, caregivers often cite the filling of portable infusion pumps (PIP). This context was conducive to achievement of the goal of the following project: the development of a motorized apparatus designed to minimize the risk of MSDs caused by repeated gestures of filling PIPs.: The development of the tool followed eleven steps including: (a) a market analysis, (b) a SWOT analysis, (c) definition of the specifications of the apparatus, and (d) a concurrent engineering methodology.: In approximately 18 months, a dynamic project group supported by a concurrent engineering methodology has designed and developed a compact and lightweight motorized apparatus able to suppress the risk of MSDs caused by manual filling of PIPs. After a mandatory step of familiarization, all involved operators have unanimously endorsed the new tool.: We believe that this new motorized apparatus may now simply and substantially alleviate occupational MSDs caused by the manually filling of PIPs. Another major benefit of this research program is the clear improvement of the intrinsically quality of therapeutic objects (TO) through the creation of a more accurate and reproducible method of PIP filling.

Abstract
Abstract: Pediatric chemotherapy preparations are usually not analytically controlled, for several reasons. First, they are generally made in syringe, which does not allow to take a sample without changing the final volume. Secondly, the percentage of the dose consecrated to control is important and finally low concentrations can cause sensitivity problems. This lack of quality control, greatly reduces the security of the chemotherapy circuit.: The main objective is to develop an analytical control to low volume pediatric preparations, made in syringes or in infusion bags with a final volume from 20 to 50 mL.: The development of analytical control automatons, like QCPrep+: Our protocol implies the overfilling with one milliliter of solvent followed by a sampling of one milliliter. The analysis is performed with 900 µL. Ten cytotoxic drugs commonly used in pediatric oncology have been validated according to ICH recommendations. The development of analytical control for low volume preparations allows young patients to benefit the same level of safety and quality than adult patients.

Abstract
Control of chemotherapies preparations are now an obligation in France, though analytical control is compulsory. Several methods are available and none of them is presumed as ideal. We wanted to compare them so as to determine which one could be the best choice. We compared non analytical (visual and video-assisted, gravimetric) and analytical (HPLC/FIA, UV/FT-IR, UV/Raman, Raman) methods thanks to our experience and a SWOT analysis. The results of the analysis show great differences between the techniques, but as expected none us them is without defects. However they can probably be used in synergy. Overall for the pharmacist willing to get involved, the implementation of the control for chemotherapies preparations must be widely anticipated, with the listing of every parameter, and remains according to us an analyst's job.
